According to national standards, the construction of domestically recognized animal houses should be managed in accordance with Class C clean areas. The items in the national standard are mostly static indicators, that is, the indicators of the animal house when no animals are introduced. There is currently no national standard for dynamic indicators. When constructing animal houses, most of them refer to the construction experience of clean animals and SPF animals. When consulting CEIDI Xidi by phone, many companies also pay attention to the design and decoration of ordinary experimental animal laboratories, but in actual operation, many experimental animal rooms The premises are all complex, and animals of all levels are raised, and they are arranged according to the cleanliness.

First of all, let's talk about the level of animals raised in the animal laboratory:

1. Class 1 common animal (CV) refers to a common animal whose microorganisms are not subject to special control.

2. Level 2 Clean Animals (CL), requiring the exclusion of pathogens of zoonotic diseases and major animal infectious diseases.

3. Level 3 Special pathogen-free animals (SPF), except for Level 2, some prescribed pathogens must be excluded.

4. Level 4 Sterile animals (GF) or gnome animals (GN). Sterile animals are required to not contain any microorganisms that can be detected by existing methods. Xisheng animals require one or several known microorganisms to be implanted on sterile animals.

For first-class ordinary animals, the breeding environment is an open system, and there is no requirement for air cleanliness. The planning should also be divided into preparation areas, breeding areas, and experimental areas. The flow of people, logistics, and animals are required to be separated (one-way flow); purification, sterilization, and insect control are required; the air conditioning system has controllable temperature and humidity, airflow speed and distribution, and a certain amount of air exchange and air pressure; lighting, no windows The animal room uses fluorescent lights, and the windowed animal room can be equipped with glass windows to filter out ultraviolet rays. It requires 12h to be bright and 12h to be dark. The water supply includes drinking water and refined water. As we said before, there are relatively few people who only raise first-class ordinary animals. Professional animal houses have higher research needs in the experimental environment, and they will also build experimental sites suitable for animals of all levels.

Precautions for animal laboratory construction (general):

1. According to the requirements of different types and levels of experimental animals, establish corresponding facilities and animal rooms, activity venues and corresponding auxiliary rooms. The site should be selected in a place that is quiet, clean and does not affect the outside world.

2. The animal room must be well-lit, well-ventilated, and the ground clean and free of water; the ceiling and walls must be easy to clean, and the exterior walls, roofs, ceilings, doors and windows, and pipes leading to the outside must be free from external animals, mosquitoes and other insect pests. Into. The indoor temperature is controlled at 18-29 degrees, the relative humidity is 40-70%, and the noise is within 60 decibels.

3. The density of animals in the cage should not be too high, and there should be air supply, exhaust, cooling and heat preservation equipment. There must be dedicated sewage and drainage facilities to prevent the spread of pathogens. Various cages should be disinfected regularly, and the litter should be disinfected at high temperature and replaced in time to keep the indoor ammonia concentration below one part per million (PPM).

Meticulous and detailed preliminary planning and design is the key to the success or failure of the animal room laboratory. How to configure animal disinfection and quarantine rooms, changing rooms, cleaning and disinfection areas, clean corridors, and dirt corridors; the construction of lighting, pressure difference, air conditioning purification systems, gas pipelines, and water supply and drainage are also highly professional. Compared with other animal room laboratory design and decoration companies, CEIDI Xidi, an animal room EPC engineering integration service provider that provides integrated services of planning, design, decoration, laboratory furniture and supporting engineering, will have more rich experience in actual construction.
